65V/4ARMS+ Fully Integrated Smart Stepper Motor Controller and Driver

The TMC5262 is a miniaturized, smart, high-power, single-axis stepper motor controller and driver IC with SPI and extensive diagnostic capabilities. Highest integration, high energy efficiency, and a small form factor enable miniaturized, scalable, and cost-effective motor drive solutions perfectly suited for Nema 17, Nema 23, and even Nema 24 steppers.

StealthChop+ ensures noiseless operation and maximum efficiency, optimal motor torque control, and dampening of mid-range motor resonances for a smoothly running motor with low mechanical vibrations. Combined with StallGuard+, CoolStep+, and μDcStep, this results in a highly efficient and versatile stepper motor driver. An unloaded Nema 17 motor automatically runs with as low as a few 10mA of supply current.

The TMC5262 combines a flexible eight-point ramp generator for automatic positioning with a smart 256 microstep motor driver and two integrated 65V, 4.25A RMS, 6A peak H-bridges plus non-dissipative integrated current sensing (ICS). ICS eliminates bulky external sense resistors, resulting in space and power savings.

The integrated power MOSFETs' low impedance of ~40mΩ ensures high efficiency and low heat generation.

Abundant diagnostics include an on-chip scope interface for tuning and checking (RT-OCSI), temperature and voltage ADC, and a full set of protection functions like short protection and thermal shutdown.

It comes in a compact, near chip-scale, thermally optimized 30-pin 6mm x 6mm FCQFN package.
